[Based on traditional Chinese medicine inheritance support system to analyze the regularity of umbilicus application to treat ascites due to cirrhosis].

Umbilicus application to treat ascites caused by cirrhosis is a simple and effective characteristic therapy. This article analyzed the regularity of application traditional Chinese medicine (TCM) herbs on umbilicus to treat ascites caused by cirrhosis through TCM inherited auxiliary system. This study chose academic literatures related to TCM dressing umbilicus to treat ascites caused by cirrhosis in CNKI database, VIP database, Wanfang database over the past 20 years as the data source, and established database to analyze the core drugs and their channel tropism, property and flavor, compatibility law, and core composition,by means of frequency statistics, and association rules (Apriori method, complicated system entropy clustering). Finally, 92 prescription to treat ascites caused by cirrhosiss were screened out. These prescription includes 109 traditional Chinese medicines. And the analysis showed that there are 14 drugs with usage frequency of 10 and more than 10, 19 common drug pairs, 12 core drug combination. The drugs with high usage frequency include Kansui Radix, Borneolum Syntheticum, Pharbitidis Semen, Rhei Radix et Rhizoma, Moschus, Euphorbiae Pekinensis Radix, Natrii Sulfas, Cinnamomi Cortex, Genkwa Flos, Phytolaccae Radix, Arecae Semen.

[Seasonal stratification and eutrophication characteristics of a deep reservoir, Longtan Reservoir in subtropical area of China].

In order to reveal the seasonal stratification and eutrophication characteristics of the subtropical large deep reservoir--Longtan Reservoir, the spatial and temporal distribution of environmental factors and eutrophic index were investigated during November (dry period) 2012, April (level period) and July (wet period) 2013. The results suggested that: (1) The stratification structure of Longtan Reservoir was meromictic lake, it had a single thermocline structure in the dry season, the surface layer to the 60 m was a mixomolimnion, 60-80 m was a thermocline, deeper more than 80 m was a monimolimnion. It had a double thermocline structure in flow period and wet period, the surface to 10 m was a mixed layer, 10-20 m was a thermocline, 20-40 m was a mixed layer, 40-60 m was a thermocline, deeper more than 60 m was a mixed layer. (2) The thermal stratification dominated the structure of other environmental factors, the stratification structure limited the water convection, especially the monimolimnion reduced the harm of the endogenous pollution. (3) The trophic level index (TLI) was 23.4-32.8 in the dry period, 27.1-38.6 in the flow period and 26.0-45.1 in the wet period, which were all Mesotropher. The trophic state index of total nitrogen was 60.3-72.5, which was eutropher to hyper eutropher, N: P was 107:1, which was phosphorus limited.

The chemokine CXCL9 exacerbates chemotherapy-induced acute intestinal damage through inhibition of mucosal restitution.

PURPOSE: Acute intestinal damage induced by chemotherapeutic agent is often a dose-limiting factor in clinical cancer therapy. The aim of this study was to investigate the effect of chemokine CXCL9 on the intestinal damage after chemotherapy and explore the therapeutic potential of anti-CXCL9 agents. METHODS: In vitro cell proliferation assay was performed with a non-tumorigenic human epithelial cell line MCF10A. Multiple pathway analysis was carried out to explore the pathway that mediated the effect of CXCL9, and the corresponding downstream effector was identified with enzyme-linked immunosorbent assays. Chemotherapy-induced mouse model of intestinal mucositis was prepared by a single injection of the chemotherapeutic agent 5-fluorouracil (5-FU). In vivo expression of cxcl9 and its receptor cxcr3 in intestinal mucosa after chemotherapy was determined by quantitative real-time PCR. Therapeutic treatment with anti-CXCL9 antibodies was investigated to confirm the hypothesis that CXCL9 can contribute to the intestinal epithelium damage induced by chemotherapy. RESULTS: CXCL9 inhibited the proliferation of MCF10A cells by activating phosphorylation of p70 ribosomal S6 kinase (p70S6K), which further promotes the secretion of transforming growth factor beta (TGF-ß) as the downstream effector. A blockade of phospho-p70S6K with inhibitor abolished the effect of CXCL9 on MCF10A cells and reduced the secretion of TGF-ß. The expression levels of cxcl9 and cxcr3 were significantly up-regulated in intestinal mucosa after 5-FU injection. Neutralizing elevated CXCL9 with anti-CXCR9 antibodies successfully enhanced reconstitution of intestinal mucosa and improved the survival rate of mice that received high-dose chemotherapy. CONCLUSIONS: CXCL9 inhibits the proliferation of epithelial cells via phosphorylation of p70S6K, resulting in the excretion of TGF-ß as downstream mediator. CXCL9/CXCR3 interaction can exacerbate chemotherapeutic agent-induced intestinal damage, and anti-CXCL9 agents are potential novel therapeutic candidates for promoting mucosal restitution.

Study on antitubercular constituents from the seeds of Nigella glandulifera.

Two new compounds with five known compounds have been isolated from EtOH extract of the seeds of Nigella glandulifera. On the basis of their spectroscopic and chemical evidence, the new compounds were elucidated as methoxynigeglanine (1) and 6-methoxythymol-3-O-ß-D-glucopyranoside (4). Compounds 1-4 showed moderate antitubercular activity against Mycobacterium tuberculosis strain H37Rv with minimal inhibitory concentration (MIC) values of 32-250 µg/mL.

Electrical stimulation of deep peroneal nerve mimicking acupuncture inhibits the pressor response via capsaicin-insensitive afferents in anesthetized rats / 中国结合医学杂志

<p><b>OBJECTIVE</b>To assess the inhibitory modulation of blood pressure by stimulation of the deep peroneal nerve (DPN) and to determine the involvement of nociceptive fibers in the modulation.</p><p><b>METHODS</b>All the animals were divided into six groups (A-F). The rats in groups A and B received no pretreatment. The rats in groups C and D received subcutaneous injection of capsaicin or control vehicle, respectively, near the DPN for 2 days. Those in groups E and F had the DPN exposed to capsaicin or control vehicle, respectively, for 20 min. Subsequently, pressor responses were induced by stimulation of paraventricular nucleus (PVN) either electrically (groups A and C C-F) or chemically via injection of glutamate (group B). After two stable pressor responses (baseline), all groups were subject to 5-min DPN stimulation followed by PVN stimulation for 10 s. Arterial blood pressure, heart rate, and electrocardiogram were recorded. The pressor response was calculated as the difference in the mean arterial pressure (MAP) before and after PVN stimulation, and changes from baseline in pressor response after DPN stimulation were compared between the groups.</p><p><b>RESULTS</b>Increases of MAP of 22.88±2.18 mm Hg and 20.32±5.25 mm Hg were induced by electrical (group A) or chemical (group B) stimulation of the PVN, respectively. These pressor responses were inhibited by stimulation of the DPN, and the MAP was reduced to 12.00±2.10 mm Hg in group A (n=6, P<0.01) and 7.00±2.85 mm Hg in group B (n=6, P<0.01). Subcutaneous injection of capsaicin (125 mg/kg) near the DPN in group C (n=7) had no effect on the inhibitory effect of DPN stimulation compared with the group D (n=9), and neither did blockade of nociceptive fibers with capsaicin in group E (n=6) compared with group F (n=8).</p><p><b>CONCLUSION</b>Stimulation of the DPN mimicking acupuncture has an inhibitory effect on the pressor response, and the effect is mediated by capsaicin-insensitive afferent fibers in the DPN.</p>
